Effect of organoclay loading on the dielectric properties and charge dynamics of a PP-rubber nanocomposite

open access: yesHigh Voltage, 2020
The addition of organoclay to a polypropylene-rubber (PP-rubber) blend, primarily introduced to compatibilise the immiscible polymer blend, invokes contrasting dielectric and charge dynamic behaviour depending on the filler loading level.
